  • tycho-versions-plugin can now be used with pom-less builds
  • Enable build of features with multiple os/ws/arch filters

 

API Certification

The project leadership certifies that the APIs in this release are "Eclipse Quality".

Non-Code Aspects

User docs: Reference documentation is generated during build and published for Tycho and Tycho Extras . Other documentation like FAQs is provided in the wiki

Example builds of eclipse plugins, tests and RCP products are kept up to date w.r.t. the latest Tycho version

Tutorials from past EclipseCons are referenced in the documentation

Localization/I18n is out of scope for Tycho as a commandline tool

 

Usability Details

Tycho does not have any user interface apart from the commandline

Communities

User community:

the project's user mailing list  continues to be pretty active with ~ 50 posts per month. Initially the committers were mostly answering but in the meantime users are helping out each other for most questions. The project's committers hosted several tutorial sessions on EclipseCon 2012 through 2014 as well as a Tycho talk for EclipseCon 2015 . 

Adopter community:

Non-committers are blogging about how they use Tycho.

Several add-ons for Tycho have been developed independently: version-tiger, jboss maven tools . Some of them made their way back upstream into Tycho.

 

Developer/committer community:

Each milestone release typically has about 4-5 patches contributed by non-committers (see release  announcements)

We were able to recruit a new committer (Martin Schreiber, bachmann electronic GmbH)

Due to the fact that Tycho is a set of maven plugins, there is a close relationship to the Apache Foundation. Many parts of apache maven like e.g. the unit test functionality surefire are reused in Tycho and patches were contributed to Maven.
